f Application filed August 6, 1907. Serial No. 387,382.

To all whom it may concern:

Be it known that I, EDWARD H. AMET, a citizen of the United States,residing at Phm'nix, in the county of Maricopa and Territory of Arizona,have invented new and useful Im rovements in Gas Apparatus, of

which the ollowing is .a specification.

This invention relates to improvements in 1gas apparatus for producing afixed gas from ydrocarbon oils, and may be'ap licable to various formsof gas producers ;v ut it has been especially designed to accompany aform of gas makingi ap aratus heretofore invented by me, an W ich isdescribed and claimed in a copendin ap lication filed by me January 21,1907, erm No.'353,384, in which the gas is roduced by admittinhydrocarbon oil and air to a dissociating 0 amber, where the oil isignited and from whence the gaseous products are conducted through acombining tube where they combine and become a fixed gas which is thenceconducted to the usual scrubber and to the engine or newly invente I theconsumption of such burner where it is to be used. Owing to the highroducing power of said newly invente gas apparatus, as compared with itssize and cost, it is more economical of space and cost of plant, andlabor to rovide producers of sufficient capacity and number to insure amaximum output atall times, than to provide large storage holders Insuch gas apparatus the'oil and air must be admitted in certain proortions for a determined quality of gas, an when' such roportions havebeen determined by adusting the valves of the a paratus, the' operationof the apparatus w l constantly produce a certain quantity of gas of thedetermined quality. To chan e the quantity without changing the qualityboth the oil and air valves must be readjusted. In case as falls belowthe determined quantity, as by cutting off the gas at the burners orengines or other place or places of consumption, all surplus as producedmust be stored or wasted; ot erwise the quality of gas will vary unlessthe valves are readjusted, thus requiring attention or I produce witheach producer a somewhat greater quantity of as than will be consumed atthe time of immediate production,-

so as to insure certainty of operation at the place of consumption. useof a holder to take-care of the surplus gas.

An object of this invention is to insure high economy and satisfactoryoperation with a'gas holder of minimum size. In case the discharge ofgas is 'at any time throttled,

This necessitates the so as to cause any inordinate back pressure withinthe producer, without changing the amount of oil admitted to theproducer, accumulations of cokeand carbon occur in the producer, thusreducing the efiiciency of the plant, and at the same time causlng avariation in and impairment of the quality of the as. b An object ofthisinvention isto provide an automatically controlled gas apparatus,

adapted to produce a determined quality of gas, under varying demands astoquantity, and to do this with minimum storage capac' ity, with minimumattention and with maximum economy of fuel; and at the same time tolprovide for keepin the producer practica y free from accumu ation ofcoke.

The invention may 'be embodied in differentforms and I shall illustratethe same hereinin the best form in which I at present con templateembodying the same.

A further object is to provide'against escape of incandescent matterfrom the apparatus.

The accompanying drawings illustrate the invention .Figurel is a sideelevation of a gas apparatus embodying this invention. The parts areshown in position with the oil cut off valve closed, the blow 'ofi valve0 en, and the holder at'the point whereit has rought one by-centerbell-crank to .the turning point for closing the oil cut off valve andis about to start the other bell-crank preparatory to closing the blowoff valve or vent for waste roducts of combustion. Fig. 2 is an enargeddetail of the means for actuating the oil valve and blow off, the artsbeing in osition for turning on the 01d and before 0 csing the blow ofi.Fig. 3 is a detail from the to sustain t leftof Fig. Fig. 4 is a detailof the blow off closed. Fig. 5 is a sectional plan of the tri pingdevice or-operating the by-center be -cranks showing the ends of thecrank arms and showing sleeve turned to throw the tripping lugs out ofcommission. Dotted lines indicate the position of parts when thetripping lugs are in position for operating the by-center bell-cranks.

1 is the gas producer comprising a dissociating chamber 2 and a combmingtube 3.

4 and 5 are oil and compressed air supply ipes and 6 and 7 theregulating valves thereor, respectively;

8 is a cut-off valve for the oi]. pipe; 9 the scrubber and 10 thewater-seal at the bottom thereof.

11 is the diving flue leading from the combining tube 3 of the producerinto the water seal 10, whence the gas escapes into the scrubber and isWashed by the usual spraying device 12, above which the usual gas outletdischarge. pipe 13 leads to the place of consumption, not shown, and toa holder 14, which rises and falls as the supply is in creased andreduced above and below the demand at place of consumption.

The cut-off valve 8 is operable by an arm 15 connected by a link 16 witha weighted by-center bell-crank 17, the weight 18 of which is sufficientto operate the valve 8.

19 and 20 are tripping lugs carried by the movable holder 14 andarranged to engage an arm 21 of the weighted bell-crank to operate thesame to shift the weight 18 of said bellcrank from 'one to the otherside of a vertie cal line drawn from the axis 22 of the bellcrank 17.

23 and 24 designates stops for the bellcrank on o posite sides, of saidvertical line he weight 18 andlimit the movement of the bell-crank tothat requisite for the operation of the link 16 and the cut-off valve 8.The link 16 is provided at its end .with a slot 25 to allow movement ofthe bell crank throughout the ascending half of its travel withoutoperation of the link.

ter bell-crank 32 corresponding to the weight ed bell-crank 17, andwhich is operable by tripping lugs 33, 34, which are arranged to shiftthe bell-crank 32 an interval after the lugs 19, 20, have shifted thebell-crank 17 at the down and up movements respectively, of

the holder 14. The purpose of this is to close the oil cut-off valvefour or five seconds, more or less, before the blow-off valve 28 openswhen the holder 14 is rising beyond a certain level,and to open the oilcut-oif valve a few seconds, more or less, before theblowoff valvecloses when the holder is descending below a certain level. i

The lugs 19, 20, and 33, 34 are preferably adjustable by means ofset-screw held collars 35, so that the interval that elapses between theclosing of the oil-valve and the opening of the blow-off, on the onehand, will .be suflicient to allow the gas in. the roducer and scrubberto pass on into the older before the blow-off, is o ened; and, on theother hand, will allow t e oil to be turned on just before the blow-offis closed, so that the atmospheric air or products of combustion in theproducer and scrubber may be expelled into the external'air by the newcharge of gas.

and is thereby connected with the holder 14. Said sleeve carries theadjustable collars 35 with their lugs 19, 20, 33 and 34.

38 is a handle to turn the sleeve to bring the lugs into and out ofoperative position.

39 is a guide for the sleeve and holder, and 40 is a guide for thevholder.

' 41 is a telltale or test pipe rovided with a valve 42 and opening fromt e gascombining and fixing pipe for the purpose of testing the qualityof the gas.

In practice, when the sleeve is turned into the position shown in solidlines in Fig. 5', the

holder 1.4 is free to rise-and fall without interference with thevalves. In starting the a paratus into operation .the sleeve will eturned out of coim'nission, thus leaving the oil out off and scrubberblow off valves free to be operatcdby hand.

The test pipe 41 provided with the valve 42 wil be opened and. then airand oil will be turned on through pipes 4 and 5 and will be ignited atthe ignition opening which is usually closed by a plug a.

36 1s a sleeve which is rotatable in arm 37 The attendant will test the.quality of gas by igniting the same at the pi e 41, and will adjust thevalves-6 and 7 unti the quality is satisfactory. Then he will close thevalve 42 and thereupon the blow off valve 28 being closed, the gas willflow through pipe 13 to the place of use, the surplus gas passing intothe holder 14 which rises as the gas accumulates therein.

When the lugs rise to a height where they can operate the by-centerlevers, the attendant will turn the sleeve, so as to bring the In thisposilugs into operative position. tion of the holder, the blow off bellcrank 22 is in position to allowthe weighted blow off valve 28 to close.Consequently the gas which flows into the producer is conducted onwardto the place of consumption and to the holder. The production of gaswill now proceed atthe full capacity for which the producer as thusadjusted is capable, and

any surplus production over the consump:

- bell-crank 32 and causes the blow-off valve tion at the place orplaces where the gas is to be used will become stored in the holder,thus causing the holder to rise and carry the finger 20 up intoengagement with the arm 21, thereby raising the arm 21 until the weight18 of the bell crank overbalances, whereupon the bell-crank 17 actuatesthelink 16 in the direction indicated by the arrow in Fig. 1,

thus to close the cut-off-valve 8, whereupon oil ceases to flow into theproducer and the production of gas practically ceases, and any v gasthat may be produced from oil already in the producer at the moment theweighted bell-crank 18 was shifted, willsbe driven out by compressed airfrom pipe 5 and into the holder. The ascending holder now causes the lug33 to throw the bell-crank 30 so as to oen the blow-off valve 28 throughwhich t e products from the producer may now escape to the open air.This relieves the air pressure in the producer so that no further supplypasses the seal s in pipe 13 while valve 281s 0 en.

If t e consumption of gas continues, gas will flow from the holder untilthe same falls sufficiently to cause the lug 19 to again shift theweighted bell-crank 17, thus opening the oilvalve to supply oil to theproducer, whereiplon 'the production of gas again begins.

- e lug 33 now acts on t e arm 21 of the 28 to close, thereby causingthe production and delivery of gas to be resumed.

The dissociating chamber 2 is made of refractory material which becomesuite hot on the inside and accumulations of co e there-v -.m' may retainan ncandescent condition for a considerable period, say twenty:.minutes, more or less, after the oil has Ibsen shut off and-combustionwill then be supplied in the chamber by the air and the accumulatedcoke, and conse uently if the holder does not remain up so ong as toallow all the coke to burn out and the interior of the producer to coolbelow the igniting tem erature, igni tion will result, and the prouction of gas will beginimmediately whenever oil is turned on at thevalve 8. The burning out of the coke at intervals \tends to keep theproducer free from clogging.
